Carousel not working?

I'm a long-time Oni fan, and just recently discovered the very cool Anniversary Edition improvements. Overall I think it's the best thing since sliced bread!

One question, though: After installing the AE, the 'carousel' cheat code no longer works. When I type it in the game displays "slow motion enabled" and "slow motion disabled," but the speed of the game doesn't change. I associate it with the AE install because that's when I noticed it happening, but I guess it's possible that the problem is somewhere else...I just can't figure out where.
